Press the λ key in the "Options" menu to select thewavelength range and the wavelength step.2. Press the upper left key to select the lower wavelength.3. Enter the lower wavelength.4. Press OK to confirm.5. Press the upper right key to select the upper wavelength.Table 14 Options during wavelength scanOption DescriptionMore Further options are displayedFolder icon To store the scan dataReference Off/OnFrom the displayed list of stored scans, a record is selected for use as a referencescan/superimposed scan. This can be highlighted or shown in the background in comparisonwith the actual measured scan.Note: This option is only available when there are stored scans with the same wavelength rangeand step.λ Enter the wavelength spectrum and scan intervalSelect ViewEnables the user to switch the display back and forth between the scan data tables(wavelength/absorbance) and the graph of the curve.Note: "Select View" will be activated after the first reading.Cursor Mode To select Track or Peak/Valley. The selection for this menu item determines to which points onthe graph the cursor moves.Send Data To send data to a printer, computer or USB memory stick (Type A)Integral: On/Off The integral gives the area and the derivative of the integral gives the original functionScale & UnitsScale: In the automatic Scaling mode, the y-axis is automatically adjusted so that the total scanis displayed.The manual Scaling mode allows sections of the scan to be displayed.Units: Choice of absorbance or transmittance.Recall measurementdata Recall saved measurement data, wave-length scans or time courses, see section 5.3, page 43.Instrument Setup mode Basic data of the instrument, refer to section 5.2, page 27.
